Opening Day for Major League Baseball in 2026 is Thursday, March 26, 2026, with a special standalone Opening Night game the day before on Wednesday, March 25, 2026.

Quick Scoop: Key Dates

  • March 25, 2026: Giants vs. Yankees in San Francisco serves as a primetime Opening Night to launch the regular season.
  • March 26, 2026: The other 28 teams play, marking the official traditional Opening Day across MLB.
  • This March 26 slate is the earliest traditional Opening Day in MLB history, not counting special or international openers.

Why This Year Is Unique

2026’s schedule is designed to start earlier than usual and still accommodate events like the 2026 World Cup, with built‑in off days and even a planned doubleheader in June to avoid conflicts in certain host cities. It also sets up a midseason highlight: the All‑Star Game on July 14, 2026, at Citizens Bank Park in Philadelphia, timed with the 250th anniversary of American independence.

For most fans, “Opening Day” will mean that big Thursday, March 26, when nearly the whole league takes the field and the long grind of the season truly begins.

TL;DR:

  • Opening Night: March 25, 2026 (Giants vs. Yankees)
  • Opening Day (full slate): March 26, 2026 — the earliest traditional Opening Day ever.
